World champions and pro athletes trust the Boulderball

Michael Piccolruaz – Olympic athlete, professional climber

As a professional climber, it’s not just raw strength that counts – your mind plays a crucial role. Focus, willpower, inner calm, stress resilience, and mental stamina are key. The Boulderball helps me train exactly those skills – and relieve stress at the same time.

Angelika Rainer – World champion, professional climber

Climbing often presents me with tricky problems that seem unsolvable at first glance. That’s where creativity comes in – just like with the Boulderball. This little tool challenges my mind, trains my fingers, and gives me fresh perspective. It’s like “pocket-sized climbing.” With the Boulderball I work on the small scale; on the wall, I use my whole body. But whether I’m on the carpet or on the rock – my mind is always active.

Christoph Vonmetz – Climbing coach

The Boulderball combines fun and training perfectly. Building the 3D puzzle helps kids train their spatial thinking in a playful way. Solving the climbing routes fosters creative strategies and teaches them to tackle complex problems. You quickly notice how focus, perseverance, and willpower grow – skills that benefit them both on the wall and in everyday school life.
